Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] In order to make the filter bag fit better with the inner wall of the stainless steel mesh and avoid wrinkles and accumulation of the filter bag inside the stainless steel mesh, people usually put their hands into the stainless steel mesh to press the side of the filter bag after putting the filter bag into the stainless steel mesh. This is inefficient and cannot be applied to some stainless steel filter meshes with smaller diameters.

[0023] according to Figure 1-Figure 4As shown, a stainless steel mesh filter bag for a filter comprises a stainless steel filter cartridge 1, a filter cloth bag 2 is detachably installed inside the stainless steel filter cartridge 1, a bag traction mechanism 3 for installing the filter cloth bag 2 is provided on the side of the stainless steel filter cartridge 1, and a bag pressing mechanism 4 for fixing the filter cloth bag 2 is provided on the upper end of the stainless steel filter cartridge 1. After the staff puts the filter cloth bag 2 into the stainless steel filter cartridge 1, the bag traction mechanism 3 will be used to pull the filter cloth bag 2 downward, and the staff does not need to press the filter cloth bag 2 manually.

[0024] Specifically, the bag traction mechanism 3 includes a rectangular vertical groove 301 that runs through the side wall of the stainless steel filter cartridge 1, and a sliding protrusion 302 is slidably connected inside the rectangular vertical groove 301. A clamping cavity 303 is provided inside the sliding protrusion 302. Two limit assemblies 304 are movably installed inside the clamping cavity 303. The limit assembly 304 consists of a sliding plate and a clamping plate. The sliding plate extends to the inside of the clamping cavity 303. The clamping plate is arc-shaped and extends to the inside of the stainless steel filter cartridge 1. When the two sliding plates approach each other under the action of the clamping spring 305, the clamping plates will move synchronously, thereby clamping the side wall of the filter bag 2. A clamping spring 305 is fixedly connected between the two limit assemblies 304. Spring 305, a sliding rod 306 is movably installed inside the sliding protrusion 302, one end of the sliding rod 306 is located inside the sliding protrusion 302, and the other end of the sliding rod 306 extends to the outside of the sliding protrusion 302. When the staff presses the sliding protrusion 302, the two limit assemblies 304 will move away from each other. When the staff pulls the sliding protrusion 302 outward, the two limit assemblies 304 will approach each other. A spherical protrusion 307 is fixedly installed on the inner side of the sliding rod 306. Initially, the spherical protrusion 307 is located between the two limit assemblies 304. When the spherical protrusion 307 is gradually moved out, the limit assemblies 304 will gradually approach each other under the action of the clamping spring 305.

[0025] Specifically, the bag pressure mouth mechanism 4 includes a mounting boss 401 fixedly mounted on the upper end of the stainless steel filter cartridge 1, a mounting circular groove 402 is provided on the upper end of the mounting boss 401, and a number of mounting circular grooves 402 are provided at equal intervals along the circumferential direction of the mounting boss 401, and a telescopic vertical rod 403 is provided inside each mounting circular groove 402, which can effectively ensure the installation stability of the movable pressure ring 404, and a pressing spring is sleeved on the outer side of the telescopic vertical rod 403, and the upper end of the pressing spring is fixedly connected to the movable pressure ring 404, and the lower end of the pressing spring is fixedly connected to the mounting boss 401. Initially, the movable pressure ring 404 will be tightly attached to the mounting boss 401 under the joint action of multiple pressing springs, and a movable pressure ring 404 is fixedly mounted on the upper end of the telescopic vertical rod 403. When the telescopic vertical rod 403 contracts, the movable pressure ring 404 will move toward the mounting boss 401, thereby pressing the opening of the filter bag 2.

[0026] In this embodiment, when installing or replacing the filter bag 2 , the staff first vertically places the closed end of the filter bag 2 into the interior of the stainless steel filter cartridge 1 , and then pulls the sliding protrusion 302 to the upper end of the rectangular vertical groove 301 .

[0027] Next, the staff will pinch the side wall of the filter bag 2 and place it between the two limit assemblies 304, and then pull the sliding round rod 306 outward. Subsequently, the two limit assemblies 304 will approach each other under the elastic action of the clamping spring 305, thereby clamping and limiting the side wall of the filter bag 2.

[0028] Next, the staff only needs to pull the sliding protrusion 302 downward along the outer side of the stainless steel filter cartridge 1 to install the filter bag 2 into the interior of the stainless steel filter cartridge 1, which can effectively prevent the filter bag 2 from wrinkling and piling up inside the stainless steel filter cartridge 1.

[0029] After the filter bag 2 has completely entered the interior of the stainless steel filter cartridge 1, the staff will pull the movable pressure ring 404 upward to separate it from the mounting boss 401, and then place the upper edge of the filter bag 2 between the movable pressure ring 404 and the mounting boss 401. Next, the movable pressure ring 404 will quickly press and fix the opening of the filter bag 2 under the action of multiple pressure springs, thereby achieving rapid installation of the filter bag 2.

[0030] The present embodiment provides a bag traction mechanism 3, and utilizes the mutual cooperation between the limit assembly 304 and the sliding protrusion 302 to help the staff quickly complete the installation of the filter bag 2, and can effectively prevent the filter bag 2 from wrinkling and piling up inside the stainless steel filter cartridge 1, which can effectively improve the replacement and installation efficiency of the filter bag 2, and there is no need for the staff to put their hands into the interior of the stainless steel filter cartridge 1 to flatten it, which can be suitable for some stainless steel filter cartridges 1 with smaller diameters; moreover, the present embodiment provides a bag pressing mechanism 4, and utilizes the mutual cooperation between the movable pressing ring 404 and the telescopic vertical rod 403, which can automatically press and fix the opening of the filter bag 2 after the installation is completed, and can also prevent the filter bag 2 from piling up or wrinkling inside the stainless steel filter cartridge 1 to a certain extent.
